Man-portable passive detection and tracking system

A method for passive detection of radio frequency (RF) signals comprising:

• receiving a plurality of signals associated with received RF signals from a plurality of receivers at a base station;
• determining cross-correlation delays between the plurality of signals;
• and
• determining a position of a source of the received RF signals based on the determined cross-correlation delays.

A system for passive detection of radio frequency (RF) signals comprising:

• a plurality of receivers configured to receive the RF signals and convert the received RF signals into a plurality of signals;
• a base station configured to:
• receive the plurality of signals;
• determine cross-correlation delays between pairs of the plurality of signals;
• determine a position of a source of the received RF signals based on the determined cross-correlation delays;
• transmit a sounding signal from the base station;
• receive a plurality of RF response signals based on the sounding signal from the plurality of receivers;
• and
• determine positions of the plurality of receivers based on the plurality of RF response signals;
• and
• a plurality of fiber optic tethers configured to connect the plurality of receivers to the base station.
